insulated for safety.

– Keep all equipment well maintained.

– The operator shall prevent gas cylinders in the

vicinity of the workpiece from becoming part of the

welding circuit.

Fumes & Gases can be harmful:

– The welding process generates hazardous fumes as

a by-product. Inhalation of these fumes is hazardous

to health.

–

– Keep your head away from the weld to avoid

breathing the fumes.

– If welding in conﬁned spaces ensure adequate

ventilation and use a fume extractor.

– Welding fumes displace oxygen. The danger of

suffocation.

– By-products of welding can react with other chemical

vapours to produce a toxic/explosive environment.

Welding can cause ﬁre or explosion:

– Arc welding and allied processes can cause ﬁre and

explosions and precautions shall be taken to prevent

these hazards.

– Before starting a weld ensure the area is clear of

ﬂammable materials.

– Remove any inﬂammables to a safe distance,

especially substances likely to generate a dangerous

vapour.

– The welding arc can cause serious burns. Avoid

contact with skin.

– Sparks and molten metal are cast out during

welding. Take precautions to prevent ﬁre igniting and

wear protective clothing.

– Sparks and molten metal can pass through gaps. Be

aware that ﬁre can start out of sight. Flammables in a

locked cabinet may not be safe.

– Do not weld pressurised containers.

– Do not weld tanks, drums, or other vessels until they

have been correctly cleaned/prepared for welding.

– Always have appropriate and fully maintained

ﬁre-ﬁghting equipment suitable for the materials used

and for use in electrical environments available in

close proximity at all times.

– Keep clothing free from oil and grease.

gloves, long sleeve tops with closed neck, trousers

(without turn-ups) to cover non-slip boots.

– Protective head and shoulder coverings should be

worn when overhead welding.

– Avoid taking any fuels with you e.g. cigarette lighters

or matches.

– Hot spots and their immediate surroundings should

be observed until their temperature has dropped to

normal.

Personal Protection:

– The body should be protected by suitable clothing.

– The use of neck protection may be necessary

against reﬂected radiation.

– Wear safety glasses when chipping, wire brushing,

grinding, or when near cooling welds as metal ﬁlings

or slag can be thrown up. Fully enclosed goggles are

advisable.

– Arc machines generate a magnetic ﬁeld which is

detrimental to pacemaker recipients. Consult your

doctor before going near welding equipment/

operations.

– The UV and IR radiation generated by welding is

highly damaging to the eye, causing burns. This can

also affect the skin. Protect the eyes and face.

– The face and eyes shall be protected by suitable

welding shields equipped with appropriate ocular

protection ﬁlters.

– Where environments are subject to pedestrians and

trafﬁc ensure a protective screen is used to avoid

accidental arc glare.

- Do not weld in the vicinity of children or animals and

ensure no one is looking before striking up.

– In the welding environment, damaging levels of noise

can exist. Wear hearing protection if the process

dictates.

– Do not touch hot equipment or metal. Allow the weld

time to cool, use the correct tool and wear protective

welding gauntlets.

– Wear ﬂame retardant clothing (leather, wool, etc.).

– Take care when adjusting or maintaining the torch

that it has had time to cool sufﬁciently and is

disconnected.

– The arc generates

• ultra-violet radiation (can damage skin and eyes).

• visible light (can dazzle eyes and impair vision).

• infra-red (heat) radiation (can damage skin and

eyes).

– Such radiation can be direct or reﬂected from

surfaces such as bright metals and light coloured

objects.

Gas cylinders:

– Gas cylinders should be located or secured so that

they cannot be knocked over.

– Shield gas containers can explode if damaged. Take

care when handling.

– Ensure gas cylinders are shut-off when not in use

and between operations.

6. ASSEMBLING THE

WELDER

Make sure the power supply information on the

machine’s rating plate is compatible with the power

supply you intend to connect it to.

A suitable plug must be ﬁtted by a qualiﬁed

electrician.

This machines wiring has insulation stripped in

preparation for wiring a 16A plug (not supplied).

It is designed for connection to a 16amp power supply

rated at 230V AC.

Because it is constructed mostly of metal parts, it is a

Class 1 machine; meaning, it must have an earth

connection in the power supply. This is to prevent

electrocution in the event of a failure.

Note: Remove the plug from the socket before carrying

out adjustment, servicing or maintenance.

Check that the electrical supply delivers the voltage and

frequency corresponding to the welding machine and

that it is ﬁtted with a delayed fuse suited to the maximum

delivered rated current.

Note: The welding machines are set to the highest

voltage at the factory.

precision control of every element of their welding.

7. SETTING THE WELDER

7.1 GENERAL

This medium weight, portable welder requires no

special lifting instructions, however, it contains

dedicated circuitry and must be handled with care. The

welder is designed to weld with coated consumable

electrodes (MMA), using a ﬁller wire feed through the

torch (MIG).

7.2 LOCATION

Locate the machine close to the correct power supply

and allow a 500mm air gap around to ensure sufﬁcient

ventilation. There are two cooling fans located in the rear

of the machine housing which must be kept clear.

Equally, ensure no debris can be drawn into the

machine.

Make certain the location does not pose any hazards as

detailed in the safety instructions, before attempting to

start the machine.

Note: Refer to the rating label for energy input details.

For TIG operations, ensure the gas bottle is securely

mounted and in a vertical position according to the

manufacturer’s instructions.

Warning! Remove the plug from the socket before

carrying out adjustment, servicing or maintenance.

7.3 MMA (MANUAL METAL ARC)

To attach the electrode holder (13) to the front panel,

insert the plug into positive coupling (10) and twist to

lock.

Attach the earth clamp (12) to the negative coupling (11)

and twist clockwise to lock.

7.4 INSTALLING THE FILLER WIRE

(MIG WELDER) – FIGS. 1 - 4

The welding machine is designed to accept the standard

size drums of wire (1kg).

The welding wire can be either of the ﬂux-cored types

this provides a means of shielding the weld pool from the

atmosphere.

Or non-ﬂux wire with the gas hose connected to the back

of the machine.

Do not let the ﬁller wire become uncoiled or tangled as

this will lead to problems with delivery to the welding

torch.

Select the ﬁller wire suitable for the parent metal and

with a gauge to match the welder speciﬁcation.

Note: If the welding machine is not regularly used,

remove the wire which is prone to rust and will cause

feed problems next time.

1. Open the side panel.

2. Unscrew the large plastic ring. Sit the reel on to the

hub (17) and make sure the peg locates in the back

of the reel. Reﬁt the large plastic ring.

–

3. Fit the wire spool so that it feeds off the base of the

reel towards the wire drive unit (18).

4. Pull tensioner (18.1) forward off the tension arm

(18.2), the tension arm (18.2) will spring up out of the

way.

FIG.

(18.2)

(18.1)

(18.3) (18.4)

5. The wire must sit in the appropriate groove for the

wire gauge. The groove size is etched on the side of

the roller. Remove nut to see the groove size that is

NOT in use. The drive roller (18.4) can be removed

from shaft, to change the groove size for appropriate

wire gauge. Unscrew and remove the retaining cap.

6. Pass the ﬁller wire through the guide (18.3) and over

the top of the drive roller, make sure the wire is well

inside the torch liner before closing the arm (18.2)

and tensioner (18.1).

FIG.

(18.1) (18.2)

(18.3)

7. Connect the welding machine to the power supply.

8. Attach the earth as illustrated.

FIG.3

9. Press the feed trigger on gun and observe the wire

feed mechanism. If the wire is being fed correctly it

will come out of the swan neck. If it jams you will

need to remove the gas shroud (9.1) and with a

small spanner unscrew and remove the tip (9.2).

Pass the tip over the wire and secure back onto the

swan neck. Do not over tighten. Resecure the gas

shroud and trim the wire back as required.

Note: Ensure the tip size matches the wire size prior to

installing.

FIG.

(9.2)

(9.1)

7.5 NO GAS WELDING PRINCIPLE

For a successful weld joint, the molten metal must be

protected from contaminating gases found in the air.

This is achieved by using a ﬂux cored ﬁller wire. The ﬂux

is produced as the wire melts.

The ﬂux creates a coating over the weld and once

cooled will need to be removed by chipping it off.

If allowed to cool naturally some areas of the ﬂux may

ping off of the weld by themselves due to thermal

contraction for this reason it is recommended that eye

protection is worn

8. BASIC WELDING

OPERATION

Note: Although this machine is medium weight and

portable take care with additional items i.e. gas bottles

etc. Do not manoeuvre over people’s heads.

8.1 WELDING TYPE SELECTION -

SWITCH – FIG.5

FIG.

Note: Welding is a mix of science and art and due to the

complex principles and vast differences in parameters

(ie. Material type, position, condition etc.) That

information is well beyond the scope of this manual.

Draper Tools suggest training be obtained from a third

party or refer to a suitable reference book on the subject

additionally; nothing can beat practice using the welder

on scrap material to get a better understanding.

8.2 SYNERGY MIG – FIG. 6

Requires just adjust welding current, other parameters

like voltage, wire speed will automatically match.

FIG.

For precise welding, adjust compensation voltage.

Micro adjustment for desired welding voltage.

Position at middle is for standard welding.

8.3 MIG WELDING PRINCIPLES

– FIGS. 7 – 8

The MIG welding process allows two similar materials to

be fused together without altering the properties of the

material. The electric arc created between the electrode

(the welding wire) and the work piece produces the

required heat for turning the metal into a molten state.

The gas creates a shield around the arc and the molten

metal.

The area to be welded and the earth point must be

clean of grease, dirt, paint and rust. Clean with a wire

brush as necessary. Position the earth clamp as close

as possible to the working area and ensure a tight grip is

achieved.

Select the welding current based on the thickness of the

material. A thick piece will require a high current,

however due to the duty cycle this will effect the welding

time by signiﬁcantly reducing it. A thin piece will only

require minimal heat and so the current can be less.

This will allow a longer period of welding. The position of

the torch is critical to the arc and end results.

FIG.

The position of the welding torch is important to achieve

a good quality bead. Position the torch at approximately

35° vertically and 75° horizontally and up to 20mm

distance from the join. 20mm is the maximum that can

be achieved on the maximum setting. Ensure the gas

shroud remains clean of spatter. Likewise and more

importantly the wire feed tip must be kept clean to avoid

the wire becoming blocked or restricted.

Use of an anti-spatter spray (Draper Stock No.05709)

will help keep the end result more tidy.

–

8.4 ARC WELDING, FILLER ROD

(ELECTRODE) SELECTION – FIG. 9

The correct selection of electrode size and type will vary

for each application dependent upon material thickness,

material type, amperage and equipment, however as a

guide the ﬁgures below provide an indication.

MMA Electrode Material Thickness Amp Range

≤1.6mm 1-1.5mm ≤50A

2.0mm 1.2-3mm 45 - 75A

2.5mm 2-5mm 75 - 110A

3.25mm 4-8mm 100 - 150A

With the MMA welding process the arc created between

the work piece and the consumable electrode rod melts

the parent metal and the ﬁller metal in a weld pool.

The electrode’s ﬂux coating reacts during this process

and develops into a shield gas protecting the weld bead.

Part of this reaction leaves a trail of slag which solidiﬁes

behind the weld pool protecting the weld as it cools.

The most common varieties of electrodes are cellulosic,

rutile and basic, the latter two being the most general

purpose.

Selection of the appropriate speciﬁcation electrode is

important to achieve a good quality weld. Seek guidance

if unsure of selection.

FIG.

8.5 MMA/ARC MACHINE OPERATION

- FIG. 10

Prepare the joint(s) to be welded.

Select the electrode suitable for the application and

insert into the electrode holder (13) while pressing lever

(13.1).

With the earth clamp and electrode holder connected,

connect the machine to the power supply. The power

display will illuminate as conﬁrmation. Set the amperage

appropriate to the selected electrode size.

Secure the earth clamp to a clean sound section of the

parent metal in the vicinity to the intended weld.

With all safety equipment in place and personal

protective clothing on begin welding.

Lower the electrode down toward the parent metal and

strike the arc.

FIG.

(13)

(13.1)

8.6 DIRECTION OF WELD – FIG. 11

Strike the initial arc perpendicular to the parent metal

before moving the electrode holder in the direction of

travel 20-30° (Z,Y axis) and tilt it 20-30° (Z,X axis).

Maintain a constant gap between the electrode tip and

the weld pool of approximately 1 to 1.5 times the

diameter of the electrode for a stable arc. This machine

is equipped with two additional features ‘Arc Force’ and

‘Anti-Stick’ to ensure smooth welding and reduce the

instances of the electrode becoming stuck to the parent

metal.

-Z

-X-Y

Direction

of weld

FIG.

Deﬁnition:

ARC FORCE

The machine will automatically create a speciﬁc

overpower when the electrode is too near, forcing it back

to help avoid the risk of sticking.

Deﬁnition:

ANTI-STICK

The machine will automatically reduce the intensity of

the current in order to aid quick and simple separation of

the electrode and parent metal.

The position of the electrode is critical to the arc and the

end result. Achieving a good weld will take practice.

For more detailed information refer to a welding book

and/or seek training on the subject.

Use of an anti-spatter spray Draper stock No.05709 will

help to achieve a cleaner ﬁnished weld. This welding

power source has a maximum material thickness

capability of 5mm.

8.7 THERMAL CUT-OUT

If welding for extended periods the thermal cut-out will

activate prohibiting use of the machine until sufﬁciently

cool.

Attention: After completion of any welding task leave

the unit connected to the power supply for a sufﬁcient

period to allow the cooling fan to continue working.

8.8 DEFINITION:

DUTY CYCLE:

Duty Cycle is a percentage of 10 mins. in which a

machine can operate at a rated load without overheating

and interruption from the thermal cut-out device.

Example: 150A @ 30% Duty factor

150A welding for 3 minutes

7 minutes down time

Example: 95A @ 100% Duty factor

95A continuous welding

To increase the operation time, reduce the amperage.

Note: The heating tests have been carried out at

ambient temperature and the duty cycle (duty factor) at

20°C has been determined by simulation

Deﬁnition:

ARC WELDING:

Fusion welding in which heat for welding is obtained

from an electric arc.

Deﬁnition:

MANUAL METAL ARC (MMA welding):

Also known as SMAW (Shielded metal arc welding).

Metal-arc welding† with straight covered electrodes of a

suitable length and applied by the operator without

automatic or semi-automatic means of replacement. No

protection in the form of gas from a separate source is

applied to the arc or molten pool during welding.

†Arc welding using a consumable electrode.

Deﬁnition:

METAL INERT-GAS (MIG welding)

Also known as GMAW (Gas metal arc welding)

A welding process in which an electric arc forms

between a consumable wire electrode and the

workpiece metal(s), which heats the workpiece metal(s),

causing them to melt, and join. Along with the wire

electrode, a shielding gas feeds through the welding

gun, which shields the process from contaminants in the

air.
